DESCRIPTION OF THE PREFERRED EMBODIMENT

Now, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, reference numeral 10 denotes a multipurpose truck as a vehicle. The truck 10 includes a pair of left and right front wheels 13 and 13 suspended in a front portion of a vehicle body 11 by a front suspension 12, and a pair of left and right rear wheels 15 suspended in a rear portion of the vehicle body 11 by a rear suspension 14. To each wheel, a low pressure tire called a balloon tire is mounted. In a middle portion of the vehicle body 11, a cabin 17 with a roof 16 is formed.

In the cabin 17, a pair of left and right seats 18 a and 18 b, and a steering wheel 19 facing one driver seat 18 a are provided, and the steering wheel 19 is steerably joined to the front wheels 13 via a steering mechanism 20. Below the left and right seats 18 a and 18 b, a power unit 21 including an engine is mounted in a frame 11F of the vehicle body 11, and power of the power unit 21 is transmitted to the rear wheels 15 via a propeller shaft 22 and a differential gear 23.

As shown in FIGS. 1 and 3, in the front portion of the vehicle body 11, a housing box 25 is mounted that houses tools or other small articles and placed in a space around the steering mechanism 20. A front hood 26 covering the housing box 25, the steering mechanism 20, and the front wheels 13 from above is openably and closably joined to the frame 11F of the vehicle body 11 via a pivot 27.

As shown in FIGS. 4 and 5, immediately above the rear wheels 15, a box-shaped loading platform 30 including an openable and closable rear gate 30 c is mounted to the vehicle body 11 so as to be dumpable rearward. Specifically, the loading platform 30 includes a loading platform frame 30F extending in a front and rear direction of the truck 10 on a lower surface, and the loading platform frame 30F is joined to a rear end of the frame 11F of the vehicle body 11 via a pivot 31 so as to be dumpable rearward. The loading platform 30 can pivot around the pivot 31 between a normal position where the loading platform 30 is horizontally supported on the frame 11F of the vehicle body 11 and a dump position where the loading platform 30 is tilted rearward. At upper left and right corners in a front wall 30 b of the loading platform 30, arcuate grips 33 used for a manual dump operation of the loading platform 30 are formed. Between the loading platform and the vehicle body 11, an auxiliary dumper 32 for assisting the dump operation of the loading platform 30 is mounted. In a lower portion at a front end of the loading platform 30, a manual lock device 34 is provided that can lock the loading platform 30 to the vehicle body 11 in the horizontal normal position.

As shown in FIG. 5, a floor 30 a of the loading platform 30 is made of steel plate, and has a number of ribs 37, 37 . . . extending in the front and rear direction of the truck 10. On the floor 30 a, a pair of front and rear load securing tools 38 and 38; 38 and 38 are provided on left and right sides. As clearly shown in FIGS. 7 and 8, each load securing tool 38 includes a support member 39 mounted to the floor 30 a, and a hook member 40 supported by the support member 39. The support member 39 includes a base portion 39 a, and a boss portion 39 b continuously connected to one end of the base portion 39 a. The hook member 40 is formed of a D-ring, and a straight-shaped shaft 40 a thereof is rotatably supported by the boss portion 39 b. At this time, between the shaft 40 a and the boss portion 39 b, friction is applied such that the hook member 40 can be held in a horizontal position, any tilted position, and a standing position.

The base portions 39 a of the support members 39 are placed so that the boss portions 39 b of the left and right load securing tools 38 face each other, and secured to the floor 30 a by bolts 42. At this time, each base portion 39 a is held between a pair of front and rear positioning pieces 43 and 43 welded to the floor 30 a and is prevented from rotating around the bolt 42. Thus, the base portion 39 a can be reliably secured to the floor 30 a only by single bolt 42.

On an upper surface of the floor 30 a, a pair of bumps 44 and 45 are formed that are arranged axially of the boss portion 39 b of the load securing tool 38 with the load securing tool 38 therebetween. The bumps 44 and 45 receive a load on the floor 30 a when placed immediately above the load securing tool 38 and prevent interference between the load and the load securing tool 38.

As shown in FIGS. 5 to 8, a floor mat for a loading platform 35 is placed on the upper surface of the floor 30 a so as to cover the entire surface. The floor mat for a loading platform 35 is made of rubber. At this time, in the floor mat for a loading platform 35, a pair of upper bumps 46 and 47 having, in lower surfaces, recesses 46 a and 47 a that receive the bumps 44 and 45, respectively, on the floor 30 a, and a slot-shaped retaining hole 48 that is formed between the upper bumps 46 and 47 and fits around the boss 39 b of the load securing tool 38 without forming clearance. On an upper surface of the floor mat for a loading platform 35, a number of anti-slip protrusions 49, 49 . . . extending in the front and rear direction in positions corresponding to the ribs 37, 37 . . . of on the floor 30 a are formed.

Thus, in placing the floor mat for a loading platform 35 on the floor 30 a, the hook member 40 of the load securing tool 38 is first kept raised and then passed through the retaining hole 48 in the floor mat for a loading platform 35, and then the retaining hole 48 is caused to fit around the corresponding boss portion 39 b. The retaining hole 48 is formed to fit around the boss portion 39 b without clearance, and the hook member 40 formed of a D-ring has a width larger than that of the boss portion 39 b. Thus, the slot-shaped retaining hole 48 is longitudinally extended when the hook member 40 is passed through the retaining hole 48, and released from the extended state after the passage, then, the retaining hole 48 contracts back to its original shape, and is prevented from coming off the hook member 40.

The hook member 40 protruding upward of the retaining hole 48 is tilted to a horizontal state to hold the floor mat for a loading platform 35 down from above, further preventing the retaining hole 48 from coming off hook member 40, and also preventing the floor mat for a loading platform 35 from rising.

Thus, the plurality of load securing tools 38 and the retaining holes 48 in the floor mat for a loading platform 35 that fit roots of the load securing tools 38 comprise floor mat securing means 50, and the floor mat for a loading platform 35 can be easily secured on the floor 30 a by the floor mat securing means 50, and thus can be easily removed. Further, there is no need for special securing members such as screws or rivets. The retaining holes 48 are die-formed simultaneously at the time the floor mat for a loading platform 35 is made of rubber by molding. Thus, inner surfaces of the retaining holes 48 are smooth and have no cut that may cause stress concentration, thereby ensuring durability of the retaining holes 48.

In conventional trucks in which a floor of a loading platform is provided with a load securing tool, a relatively large notch that does not interfere with the load securing tool is generally provided in a floor mat for a loading platform in the case of placing the floor mat for a loading platform on the floor. Thus, a small article (for example, a screw or the like) having fallen on the floor mat for a loading platform may enter between the floor and the floor mat for a loading platform through the notch and be lost. In the present invention, however, the retaining hole 48 in the floor mat for a loading platform 35 fits around the boss portion 39 b of the load securing tool 38 without clearance as described above, thereby preventing a small article from passing through the retaining hole 48 and being lost.

In the floor mat for a loading platform 35, the upper bumps 46 and 47 are formed that are raised on the front and rear of the hook member 40 exposed from the retaining hole 48, and receive the bumps 44 and 45 on the floor 30 a. Thus, even when a load to be placed on the floor 30 a is placed immediately above the load securing tool 38, the upper bumps 46 and 47 receive the load to prevent interference between the load and the load securing tool 38 and prevent damage to the load.

When the load on the floor 30 a is easily moved, a rope or the like for retaining the load is threaded through the hook members 40 of the plurality of load securing tools 38 to prevent movement of the load. At this time, a number of anti-slip protrusions 49 and 49 . . . on the floor mat for a loading platform 35 made of rubber provide an anti-slip function and a cushioning function to prevent movement and vibration of the load.

The present invention is not limited to the above described embodiment, and various design choices may be made without departing from the gist of the present invention. For example, the floor mat for a loading platform 35 according to the present invention may be used for a luggage chamber of a passenger automobile. The mat 35 may be made of material having stretchability such as to extend the retaining hole 48 and insert the hook member 40 through the retaining hole 48, and may be made of rubber, woven fabric, resin, and combinations thereof.
